Pitch deck structure: the 13 slides investors expect, in order

An investor in Milan opens your PDF on a Tuesday evening, between two other decks and a plate of pasta going cold. DocSend, which tracks how decks shared through its platform are read, puts the average at 4 minutes and 10 seconds for a pre-seed deck. In its 2022 data, investors gave up on decks that went on to fail after just 2 minutes and 13 seconds. So your pitch deck structure has about four minutes to work, and sometimes just over two.

We’ll go through 13 slides, in the order most investors read them. Each gets the job it has to do, a one-line example from an invented startup and the mistake that sinks it most often. Then comes the live version, which isn’t quite the same deck, and a checklist for the night before you press send.

How many slides should a pitch deck have?

Fewer than you think. Start with the market you’re pitching into: in 2025, 436 venture rounds closed in Italy and 354 investors took part in them, according to Growth Capital and Italian Tech Alliance. Each of those investors reads decks fast and in the same order, looking for the same answers.

Sequoia’s classic template has ten sections. DocSend’s pre-seed research suggests 12 sections over about 18 pages. The European Commission is stricter. The short application to the EIC Accelerator, its startup funding programme, takes a PDF deck of ten slides at most, plus a video pitch of up to three minutes.

For a first round, stop at 14 slides. Ten is fine. Whatever answers a question nobody has asked yet goes into an appendix after the last slide: detailed financials, the full roadmap, how the technology is built.

Pitch deck structure: the 13 slides in order

Think of the order as the questions running through an investor’s head. What does this company do? Does the problem matter? Why now? How big can it get? Does anyone want it? Then the money part: how does it earn, can you win, and what do you need? Sources differ on a few positions. DocSend’s suggested order puts the team right after the market slide, and Sequoia places competition before the business model. Treat this as a default, and move a slide forward when it’s your strongest card.

Slide	What it must prove	Common mistake
1. One-liner	You can say what the company does in one sentence.	A logo and a slogan, no explanation.
2. Problem	A specific group has a frequent, costly pain.	A problem only the founders feel.
3. Solution	Your answer removes that pain, simply.	Features instead of the outcome.
4. Why now	Something changed that makes this possible or urgent today.	Skipping it, or “the market is growing”.
5. Market	The opportunity is big enough, counted bottom-up.	“1% of a €50 billion market.”
6. Product	It exists and it works.	Raw screenshots nobody can read.
7. Traction	People want it: users, revenue, pilots, growth.	The best number hidden on slide 12.
8. Business model	Who pays, how much, how often.	Three revenue models “to be tested”.
9. Competition	You know the alternatives and why you’ll win.	“We have no competitors.”
10. Go-to-market	You know how the first 100 customers will find you.	“Social media and partnerships.”
11. Team	These people can build and sell this.	Job titles with no relevant experience.
12. Financials	The plan holds together and matches the model.	A hockey stick with no drivers.
13. The ask	How much, for how long, to reach which milestone.	“Raising between €300k and €1M.”

Slides 1 to 4: what it is, and why now

Let’s build a deck for an invented startup, the one we used in our guide to the startup one-liner: Lievito, two founders in Bologna, software that tells small bakeries how much bread to bake each morning. Every number about Lievito is made up for teaching.

1. One-liner. Sequoia’s instruction is the whole brief: “define your company in a single declarative sentence.” Example: “Lievito helps independent bakeries throw away less bread by telling them every evening how much to bake.”

2. Problem. Sequoia asks how the pain is handled today “and what are the shortcomings to current solutions.” Example: “Bakers set tomorrow’s quantities by gut feel, and unsold bread is binned or given away at closing.”

3. Solution. Outcome first, mechanism second. Example: “One number per product, every evening, from the shop’s own receipts, the weather and local events.”

4. Why now. “The best companies almost always have a clear why now?”, Sequoia writes. Why didn’t someone build this five years ago? Maybe a technology got cheap, a rule changed, or a habit shifted. Example: “Our pilot bakeries’ tills only started exporting hourly sales last year. Before that, the data didn’t exist.”

Slides 5 to 8: market, product, traction, business model

5. Market. Investors will ask for TAM, SAM and SOM. TAM is everyone who could ever buy. SAM is the part of that group you can actually serve. SOM is the share you can realistically win in a few years. Count them bottom-up. Seibel’s method is to “figure out where comparable products are sold, how many of them are sold, and what % of those sales you could take.” The top-down trap, he says, is “not narrowing down the customer enough.”

Now Lievito, with invented numbers. Say Italy has 10,000 independent bakeries, and Lievito charges €59 a month, which is €708 a year. The TAM is 10,000 × €708, about €7.1 million. The SAM is the 3,000 shops in the north whose tills export data: about €2.1 million. The SOM is the 400 shops two salespeople can sign in three years, about €283,000 a year. Small? Then the slide also says how it grows (pastry shops, other countries). A modest number you can defend is worth more than a huge one you can’t.

6. Product. In DocSend’s pre-seed data the product section holds attention for 77 seconds, second only to the business model. Show it working, with two or three captioned screens or a link to a one-minute video. Kevin Hale, then a YC partner, warns that screenshots are “almost always illegible”, so crop them and enlarge the part that matters.

7. Traction. Your best evidence that people want it, what investors call traction. Put the strongest number in the slide title: “Four bakeries, daily use since March, a quarter less waste.” Which metrics count depends on your model, and our guide to the startup metrics investors want breaks them down by type of business.

8. Business model. Who pays, how much, how often. It gets the longest look in DocSend’s pre-seed data, 83 seconds. Seibel’s advice fits in four words: “Own the simple business model.” Example: “€59 per shop per month, billed yearly, no setup fee.” If you can, add what a customer costs to win and what they’re worth over time; our explainer on unit economics shows how to work both out.

Slides 9 to 13: competition, go-to-market, team, financials, the ask

9. Competition. Sequoia asks for your “direct and indirect competitors” and a plan to win. For Lievito the real rivals are a spreadsheet, the baker’s own instinct and the forecasting tools big chains buy. Skip the chart with you alone in the best corner. A plain table of what each alternative does badly says more.

10. Go-to-market. How will your first 100 customers hear about you, and why will they buy? That’s your go-to-market plan. Name the channel and put a price on it. Example: “Bakers’ associations in Emilia-Romagna, two field reps, first month free.”

11. Team. DocSend found a team slide in every deck it analysed in 2022, successful or not, so having one proves nothing. What matters is why these people, for this problem. Example: “Giulia ran her family’s bakery for six years; Marco built demand forecasts for a logistics company.”

12. Financials. At pre-seed a one-slide summary is enough: revenue, costs and cash over the next three years, built from the same drivers as your financial model. Sequoia’s template just says “If you have any, please include,” and DocSend calls the section optional at pre-seed. Still, in its 2022 data none of the failed decks had financials. Whatever you show must match the spreadsheet to the euro.

13. The ask. How much, for how long, to reach what. Geoff Ralston’s YC guide suggests saying you’re raising for a set number of months “and will thus need $X”. Example: “€400,000 for 18 months of runway (the months of cash you have at your current spending): 55% product, 30% sales, 15% buffer. Goal: 300 paying shops.” Investors will ask about price next, and our guide on how much equity to give away at seed has the usual ranges.

Sent by email or presented live: one structure, two decks

The deck you email and the deck you present shouldn’t be the same file. Ralston asks for “a coherent leave-behind”, a deck that makes sense when you aren’t in the room. Hale’s rules are for the room itself: slides even people in the back row can read, “one idea” per slide, a point a stranger gets instantly. “Investors invest in teams not slides,” he adds.

So keep one structure and make two versions. The send-ahead deck has full-sentence titles and enough words to stand alone. The presenting deck has a few words and big visuals, and your voice carries the rest.

Checklist: before you hit send

1. 10 to 14 slides, with the details moved to an appendix.
2. Slide one says what you do in one sentence, not just your logo.
3. Every slide title is a sentence that states the point.
4. Market counted bottom-up, with a source next to each number.
5. Your best traction number sits in a title by slide 7.
6. Financials that match the model exactly.
7. An ask with the amount, the months it buys and the milestone it reaches.
8. A file name with your company and the date (lievito-2026-10.pdf), not deck_final_v7.
9. Hand it to a friend from another industry. If they can say what you do afterwards, you’re set.
